Bowmalloy BOWMP36175 Hex Head Cap Screw 3/4-10 Grade 9

Product Description

The BOWMALLOY BOWMP36175 is a Grade 9 steel hex head cap screw in a 3/4-10 thread size with a 2-3/4 inch length under head. It features partial threading and a proprietary Bowma-Guard finish, which provides corrosion resistance in demanding service environments. This fastener is built to Grade 9 specifications, meaning it carries higher tensile strength than standard Grade 5 or Grade 8 hardware. It is used by millwrights, industrial mechanics, and maintenance trades wherever a high-strength inch-series hex cap screw is required. The Bowma-Guard finish sets it apart from plain or zinc-plated alternatives in corrosive or outdoor-exposed applications.

This screw is suited for heavy industrial and structural fastening applications where Grade 9 strength is specified. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for bolted connections where alignment and shear resistance matter. It is commonly installed in equipment frames, structural steel assemblies, and heavy machinery mounts. Mechanics and industrial tradespeople working to ASME or OEM fastener specifications will find this part a direct fit when a 3/4-10 x 2-3/4 inch Grade 9 hex cap screw is called out.

Key Features

• Grade 9 steel construction for high tensile strength beyond standard Grade 8 hardware
• 3/4-10 UNC thread form in inch measurement system
• 2-3/4 inch length under head with partial threading for shear-load capability
• Bowma-Guard finish for enhanced corrosion resistance versus plain or zinc finishes
• Hex head drive for standard hex socket or open-end wrench installation

Compatibility

Designed as a high-strength replacement or service fastener for any application calling out a 3/4-10 x 2-3/4 inch Grade 9 partially threaded hex head cap screw in inch-series hardware specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following applicable torque specifications from the equipment OEM or a recognized fastener standard such as ASME B18.2.1. Always confirm the mating thread and material compatibility before installation. Use calibrated torque tooling to achieve the specified clamp load without over-torquing. Inspect the mating threads and seating surface for damage before fastening.
